In either case, x64 should be working same as x86 version, except for external codec libraries, such as CELT and Speex. Only MP3 encoding/decoding is currently supported in x64 version, with help of lame_enc.dll and libmpg123-0.dll libraries. All built-in codecs should be working fine in x64.

Unfortunately x64 release has a bit different registration module, so you will need a separate serial for it. If you already have a license for x86/ANSI version, please contact us for a free x64 license.
